Apple has implemented all of the required parts of the IPP 3D Printing Extensions - the current prototype is available at:
The "examples" directory contains sample 3MF files from the 3MF Consortium's Github samples repository, along with an ipptool test file (create-job-3d.test) that can be used to test a prototype.
One additional issue was found during prototyping:
- There is no way to tell the Client that the Printer can reproduce multiple colors (not just the material color)
Proposal: Add "color-supported (boolean)" Printer Description attribute (standard attribute for 2D printing)
